Subject:
SGP/SIRS/E9 - Sensor cable failure
DataStreams:sgpsirs20sE9.a0, sgpsirsE9.b1, sgpsirsE9.00
Description:
The short_direct_normal measurements from the normal incident pyrheliometer (NIP) 
instrument were missing beginning 6/13/2005 2115GMT.  On 6/20/2005 technicians found the NIP 
instrument cable broken, replaced it, and returned the instrument to service at 2200GMT.
Suggestions: 
Disregard data during this period.
Measurements:sgpsirsE9.b1:
  • Shortwave direct normal irradiance, pyrheliometer, minima(short_direct_normal_min)
  • Shortwave direct normal irradiance, pyrheliometer(short_direct_normal)
  • Shortwave Direct Normal Irradiance, Pyrgeometer, Standard Deviation(short_direct_normal_std)
  • Shortwave Direct Normal Irradiance, Pyrheliometer, Maxima(short_direct_normal_max)
